Hi Nick,

What´s your xQ1 value?

Regards,
Juan

Juan hi,
I don't think my BIOS has an xQ1 setting so I'm not sure what to set on this one, try a few values and have a listen.

Cheers Nick.

Hi Nick, the xQ1 value I was asking for is the one in XXHighEnd, I don´t see it in your signature.

Regards,
Juan

Juan hi,

Q1 of 10 with SFS at 1.6mb. Gives a very dynamic sound.

Cheers,

Nick.

Thanks Nick, I understand that you have both Q1 and xQ1=10. With your Q settings the minimum SFS I can get is 14Mb.

Following your changes in the BIOS I found these as my best settings:

CPU Frequency: 1995MHz
DRAM Frequency: 1066MHz

Best regards,
Juan

Juan hi,

Regards SFS, 14mb does not seem very low for the power of your PC. I had a problem a couple of times where I could not get SFS below 4 without breaks in music. I had to go back to full OS then re minimise in XX for another reason after I did this SFS worked down to 1.5mb. It might be worth trying this to see if you can go lower.

Regards,

Nick.

Hi Nick,

I only can go that low with this Q settings:

Q1:10, Q2,Q3,Q4:0, Q5:2 and xQ1:1

This is the reason why I asked you what was your xQ1 (Q1 Factor) setting. With Q1:10 and xQ1:10 for me was impossible to go lower than SFS:14Mb

Now, with the new settings I can go as low as SFS:1,4Mb

Would you please check again your xQ1 setting?, I thing that must be a misunderstanding about it.

Tomorrow I´ll play music at normal volume level to see the SQ with this settings, now is too late here.

Best regards,
Juan

Because the mounting holes of my computer case are at the top I turned the case upside down and turned the HD and DVD too.

Thanks Georg. You turned me upside down too until I get a new case!

Had a good "listen" last night. Best ever, one would think I mounted a turntable somewhere inside the PC. Is it the speed of DVI that makes such a difference?

I will never use that sh*t VGA again. Without thinking about I connected the TV to the PC via the VGA interface. What a big mistake! When the monitor is connected via DVI the music is more analogue again and the locating phantastic. Many thanks for the reminder of the DVI interface  Happy

What I'm wondering is has the use of DVI for video operation been known to help SQ or, Nick, did you just stumble into this discovery? Really, it has been one of the most significant tweaks I've ever experienced with my system. Have others tried this too? Perhaps Nick, Georg and I happened to drink from the same batch of cool aide? It's sort of weird that others have had nothing to say about this.  scratching

I've been using the DVI (and a fanless psu) from the very beginning. Coincidental ignorance I must admit, but it turned out right  blush1.
